Acceleration waves in a spherical oscillating gas bubble containing a gas mixture

Abstract

The non-equilibrium phenomena that characterize the dynamics of an oscillating bubble in a liquid are generally very complex. In this work we study the effects produced by the presence of a gas mixture in which the temperatures of each species are taken into account. Acceleration waves are used to test the stabilizing effects of the model and verify the possibility of shock formation within the bubble. It is shown that the diffusion associated with the presence of multiple temperatures cannot be neglected when describing what happens inside the bubble, even in the sonoluminescence regime.
